The TA stapler is an advanced medical device primarily used for tissue stapling and cutting in surgical procedures. During a hepatic lobectomy, the TA stapler can precisely cut liver tissue while simultaneously suturing it, effectively reducing surgery time and the risk of bleeding. Its operating principle involves compressing the liver parenchyma between the stapler's anvil and cartridge, then releasing the stapler to complete the cutting and stapling of the tissue.
During surgery, the doctor first locates the affected lobe of the liver through precise imaging examinations and surgical navigation, and then liberates it from adjacent structures (such as the diaphragm, kidney, and gallbladder).
Choose the appropriate size of the TA stapler based on the width of the liver lobe to be resected. Before resection, the diameter and thickness of the liver lobe can be reduced using finger pressure or pre-placed instruments to facilitate the use of the stapler.
Place the TA stapler at the base of the liver lobe near the hepatic hilum, then press the proximal lever to compress the liver parenchyma between the anvil and the stapler cartridge. After releasing the stapler, the liver tissue cutting and suturing will be completed.
After the liver lobe is resected, carefully inspect the stapling site for bleeding. If necessary, use surface hemostatic agents or omental patching to achieve hemostasis.
The TA stapler can simultaneously cut and suture, effectively reducing the risk of bleeding during surgery.
The use of the TA stapler can significantly shorten surgery time and improve surgical efficiency.
Precise cutting and suturing help reduce the occurrence of postoperative complications, such as biliary tract injury and infection.
After a hepatic lobectomy, the patient should receive close monitoring and care. This includes regular checks of mucosal color, pulse, and capillary refill time to monitor for internal bleeding. Additionally, biochemical indicators such as blood sugar, intravenous fluids, and glucose should be monitored for continuous supportive treatment. Postoperative hypoproteinemia typically normalizes within 2-3 weeks, and patients should continue using antibiotics for a period based on bacterial culture and sensitivity test results.
The TA stapler has significant applications in hepatic lobectomy, reducing bleeding, shortening surgery time, and lowering the risk of complications. Meanwhile, postoperative care and monitoring are essential to ensure the success of the surgery and the patient's recovery.
